But what you didn’t see was office workers, tourists and convention-goers who regularly pound the pavement looking for lunch or a happy hour. It’s a scenario that is playing out across Baltimore.

"Guests that are staying in the hotels, they don't want to leave the hotels. They don't want to go two, three blocks," said restaurant owner Derrick Vaughan.

For Vaughan, that means a 30 percent drop in business at his Corner Bistro and Wine Bar. And he's not alone.

"Everyone -- Little Italy -- all of us have been affected. Charles Street, Sotto Sopra -- everyone has been affected and it's not good," he said.

"Our hoteliers, we've all lost a little bit of business. We've had a couple of convention cancellations here," said Tom Noonan, president CEO of Baltimore.

Noonan said the loss of the two conventions were in the city setting up when they decided to pull the plug.

"At one point they were definitely going to stay, and then Monday happened and they decided (to cancel) for the safety of their attendees," he said.

Noonan said those losses alone will cost the city an estimated 2,500 visitors and an $1.4 million economic impact.

"We hated losing any business, but the reality is that there are bigger issues than $1.4 million. It's more about making sure that if anyone's going to be here, they're going to have a great experience. They're going to have a safe experience," Noonan said.

Vaughan said he is trying to do his part to by banding together with other business owners to create Charm City Business Strong.

"Charm City Business Strong is going to be a campaign that we're going to push. And we're going to push it because we're going to need it because we're going to have to help fix the brand that has taken a hit today, and God knows how long that hit's going to take," he said.

One convention did decide to stay. The Food Safety Conference is going on right now.
